Definitions

  • the present invention relates to a glass-topped cooking unit. More particularly this invention concerns a gas fired glass cooktop.
  • a stove or cooktop having an upper surface formed by a heat-resistant glass panel.
  • a burner plate spaced underneath this panel is provided with a plurality of gas burners each positioned under a specific separately marked location of the overlying ceramic panel. Gas issuing from these burners is ignited to heat the respective locations on the panel. Normally a vent passage is formed that opens into the upper compartment formed between the burner plate and the glass panel to allow gases to be vented.
  • the burner plate is insulated heavily around the burners to protect underlying components of the cooker. Gases are vented from the stove wholly by convective action. As a rule relatively delicate components are housed in the stove underneath the burner plate and these components must be protected from the heat of the burners. Even with substantial insulation of the burner plate, these components are often subjected to substantial heat stress.
  • Another object is the provision of such an improved glass-topped cooking unit which overcomes the above-given disadvantages, that is which protects the fragile electronic components from heat.
  • a cooking unit has a housing having a front and a rear and formed at the rear with an upwardly open upright vent passage, a ceramic panel on the housing defining a plurality of cooking spots, a burner plate in the housing spaced underneath the panel and defining therewith an upper compartment opening upward into the passage, and respective gas burners supported on the plate underneath the spots.
  • An equipment plate in the housing spaced underneath the burner plate defines therewith an intermediate compartment also opening upward into the passage and defines beneath itself in the housing a lower compartment that is open to the outside at the front of the housing.
  • Control equipment is mounted in the lower compartment of the housing along with a blower having an intake in this lower compartment and an outlet in the vent passage.
  • This blower is powered, normally electrically, so as to draw a primary stream of air in from the front of the housing and through the lower compartment and to expel it upward into the passage.
  • This primary current aspirates secondary streams of air from the upper and intermediate compartments by venturi action.
  • the electronic components in the lower compartment are actively cooled by incoming outside air.
  • the combustion gases from the upper compartment are mixed with the primary ambient-air stream so that the overall temperature of the exiting gases is substantially reduced.
  • the equipment plate is at least partially insulated. It does not need substantial insulation and the burner plate can be wholly uninsulated sheet metal.
  • the blower is has a drum extending generally the full width of the cooking unit inside the lower passage.
  • the rear vent passage extends the full width of the cooker, and the outlets of the upper and intermediate compartments into the passage are also full-width.
  • the primary stream passes through the blower and is full-width where it enters the passage.
  • the intermediate compartment is provided with an outlet opening into the passage and formed with upwardly directed venturi vanes.
  • the upper compartment is provided with an outlet opening into the passage and formed with upwardly directed venturi vanes and is provided forward of the respective outlet with flow-interrupting baffles of an insulating material.
  • the cooking unit is provided with a main on/off switch and the blower is connected to the switch such that it is powered whenever the switch is on.
  • a temperature-sensitive device in the lower compartment powers the blower whenever the temperature in the lower compartment exceeds a predetermined upper limit. This temperature-responsive switching can be in addition to the regular switching as the stove is turned on and off to keep the blower running after the stove is shut off until it has cooled down.
  • FIG. 1 is a partly diagrammatic vertical section through the stove according to this invention.
  • FIG. 2 is a large-scale and partly diagrammatic view of the detail indicated at 2 in FIG. 1.
  • a stove 1 has a housing 21 with an upper surface formed by a glass panel 2 underneath which is provided a burner plate 3.
  • Individual burners 4 are set with respective nozzle plates 5 into the burner plate 3 which itself forms an upper compartment 13 with the lower surface of the ceramic panel 2.
  • the upper surface of this panel 2 is marked above each of the burners 4 with a ring to indicate the respective cooking location.
  • an insulated horizontal equipment plate 7 Spaced underneath the burner plate 3 is an insulated horizontal equipment plate 7 defining with the burner plate 3 an intermediate compartment 12 and defining underneath itself a lower compartment 8.
  • the housing 21 of the stove is formed at its front side (to the left in the drawing) with vent openings 23 at the compartments 8 and 12.
  • Electronic control equipment 9 is mounted in the compartment 8 to the underside of the plate 7.
  • the housing 21 forms at the extreme rear of the stove 1 a vertically extending vent passage 10 opening downward to the outside at 18 (FIG. 2) and opening at its upper end at holes 20 which may be connected to an exhaust duct.
  • This passage 10 extends the full width of the stove, that is perpendicular to the planes of the views of FIGS. 1 and 2.
  • the lower compartment 8 is provided at its rear side with a drum-type blower 11 whose intake draws a primary stream of air into the compartment 8 via the vent holes 23 and whose output directs this primary stream upward in the passage 10.
  • the intermediate compartment 12 is provided with full width of its rear end with an upwardly directed vane 14 defining an outlet 15 opening upward into the passage 10.
  • the upper compartment 13 similarly has a vane 16 and opens upward into the passage 10 above the outlet 15.
  • the gases issuing from the upper compartment 13 include spent combustion gases and are deflected over baffles 17 formed of insulating material.
  • the blower 11 is normally controlled by the main on-off switch 22 of the stove 1.
  • the control equipment 9 is also provided in the compartment 8 with a temperature sensor 19 that turns the blower 11 on whenever the temperature in the compartment 8 exceeds a predetermined threshold, normally about 40° C.
  • This temperature control is independent of control via the switch 22 so that the blower 11 will continue to operate even after the stove 1 is shut-off, until it has cooled down.
  • the compartments 8 and 12 are actively cooled and ventilated. Excessive heat build up and damage to potentially fragile electric components of the equipment 9 are avoided.
